Do you drink coffee? Do you have a garden?
Don't throw those grounds in the trash or garbage disposal! Coffee grounds are wonderful, and often overlooked, compost material. If you don't drink a lot of coffee, you might be able to get some from your local coffee shop. "Certain" big name coffee shop chains will charge you for their grounds, which I completely don't understand. But, most locally owned coffee shops will gladly surrender their used coffee grounds. If you've picked up one of the frosting buckets mentioned earlier, these are great for transporting soggy grounds between store and home.
